... and my penguns :P

The basic idea is to have a "universal" pistol grip and ignitor setup that you can attach to the chamber via the schrader thread, with the ignitor accessible because piezos tend to wear out eventially.

Hmm... interesting. I like the idea of being able to swap out different launcher designs... I can't wait to get home and back to building again.

I think the key is to make things modular. I don't see the point of putting the effort into finishing a launcher that might screw up internally and cannot be repaired.

Exactly. Modularity (is that even a word) is extremely useful in developing a testbed actual gun.. but still easy to prototype something.

I actually wanna bounce an idea off of you-- I've been thinking. if you put two thick rubber washers into the union- you may be able to make an almost bolt action out of it. If you add a handle to the lug, then you can just turn it possibly a quarter-half turn, and then possibly move it forward so the handle locks in place. That way, it makes the gun more "gun-like", and saves a bit of hassle of threading a union.

What do you think?

... a sort of "bolt action cam-lock"? It could work, provided the handle was long enough to provide enough leverage for a tight lock. Hmmm...

Exactly.. that's pretty much what I had in mind. i don't see why it wouldn't work- yea you'd have to be able to get some leverage, but it would make the action of reloading a bit more like a gun, and easier in that you don't have to thread the union all the way.

If you could get it to only need a quarter or a half turn, it could easily be similar to many bolt actions out there today.

This comes to mind- http://www.thefirearmblog.com/blog/2009 ... mg-pistol/

Yes, it's a segment from a longer clip

Yes - cam-locks work, and this is simply the same idea with different geometry.

You could possibly add a second lever to both minimize the stress on the single lever but mainly provide an equally tight grip on each side of the bolt/camlock mechanism.
The second lever wouldn't even have to stick out
